Now that we've gone over what you'll need to spec in the skill tree, it’s time to put it all together with the gear

Qaudimizer

The qaudimizer is a legendary rocket launcher, it fires four projectiles in a horizontal line, it cycles between corrosive, incendiary, and radiation damage.

The breath of the dying

The breath of the dying is a legendary assault rifle. In the Endgame, radiation deals 50% less damage to armor, so it pays to have a reliable way to chew through those yellow bars, and there’s no gun better for the task then the breath. It shreds armor, and when it kills an enemy, balls of acid shoot outwards from the brand new corpse! it’s pretty great

The hellwalker

The hellwalker is a legendary Shotgun, it always comes in incendiary, it’s good to diversify your damage types for this build especially, and this gun is damn fun anyways, it shots assume the form of a pentagram, and (more importantly) every time you shoot, a short piece of the doom 2016 theme will play. So much yes.

The Pestilence

The Pestilence is a legendary COV pistol, it always deals radiation, and when it breaks, irradiates the vault hunter, this aspect is integral to this build.it, synergizes beautifully with the artifact prefix that makes this build incredible

The Elemental Projector

The elemental Projector is an artifact prefix that increases the elemental damage you deal when infected with that same damage. I've personally only gotten this on legendary artifacts, but it can appearear in purples and other rarities, the legendary variety provides an additional 183% damage with the given element. This makes the pestilence the best weapon you have, and makes this build super fun. If you can, try to get an Elemental Projector Victory rush

The Red Suit 

The Red Suit is a legendary shield that provides you with immunity to rad damage, it also constantly deals radiation damage to everyone around you, this leaves you with zero drawbacks to using the pestilence extensively 

The Recurring hex

The hex is a legendary grenade that hones in on an enemy and then engulfs the area with its element, the recurring hex causes the grenade to split into three shortly after being thrown, and another three on impact. Getting this grenade in any element is great, especially the radiation for the purposes of this build 

The Bounty Hunter

The bounty hunter legendary class mod gives FL4K a 3% chance to activate any purchased Hunt Kill Skill when dealing gun damage. Bosses are now treated as humans, beasts, and robotics for FL4K's Hunt Skills. It comes with points to frenzy, hunter’s eye, and the most dangerous game

Build 2: Thanatos

Thanatos build tree

Ah the crit build, infamous at this point in borderlands 3’s life Despite 2 nerfs and counting, the crit build is still very viable, and still a whole lot of fun , this build is all about raw damage, if you want to one-shot almost everything you see, this build is the way to go. Now for the skills that put it all together.

  • Turn tail and run: while moving, FL4K constantly regenerates health, and gains damage reduction, while standing still FL4K gains gun damage and fire rate

  • Unblinking Eye: Successive hits on the same target increase FL4K’s critical hit damage by 75% per hit. This resets after 3 hits  

For this build, FL4K’s pet will be the gunslinger jabber, which gives FL4K increased movement speed and critical hit damage, when FL4K issues an attack command, the Gunslinger equips a rocket launcher and fires it at the target, now that we’re all through the skills, time to equip some ridiculous weaponry
